To all 'whom '15 may concern: i

Be it known that I, OWEN T. Bucs, a citi zen of the United States, and a resident of Hoboken, county of Hudson, and State of New Jersey, have made a new and useful Invention in Tires or TubesI for Wheeled Vehicles, of whichvtli'e following is a specification.

My invention is directed particularly to what is known in the art as tire tubes adapt'- ed to be used in connection with auto cars, trucks and the like, and which are subjected to terrific strains and pressures when running at great speeds and when carrying relatively heavy loads.

The invention will be understood by re ferring tothe accompanying drawings, in which, s

Figure l is a vertical sectional view through one form of my invention illustraty ing it as combined with an outer tire or shoe. Fig. 2 is a plan view looking upward at Fig.' l uponthe supposition that the outer tire or slice and also a portion of the inner tire 4are removed. Fig. Sis a longitudinal section of Fig. l on the line X-X and as seen looking thereat from left to right in s the direction of the arrows, showing also a portion of the complete tire as it would appear in circular form when completed.

My invention consists in making a tire for wheeled vehicles of superimposed concentric layers of soft rubber, the alternate layers being respectively perforated and unper` forated, and the whole sealed together by a self-sealing cement, or by any well known equivalentv ineans adapted to sealthe open ends of the perforations, so as to constitute heinietically sealed cells, and in joining, the en ds of the layers together around the wheel. This tire may be used either as afcomplete operative tire or as an inner tire or tube, as preferred.

In order that my invention may be fully understood so that those skilled in the art may construct and use the same, reference is had to the accompanying drawings in which l. have shown a preferred forni.

l (Fig. l) represents an outer vehicle tire or shoe of well known form, made of the usual'u'iaterial and adapted to be applied to a vehicle felly in the well known manner, the inner tire which constitutes niy invention being made of a series of strips of soft rubber or equivalent yielding material 2., 2, 2, there being` .tive of such strips shown.'

I"lilie perforations Il inthese strips may alternate in succession, as shown iii all of the figures of the drawings, and particularly .in Fig. 2, by dotted circles andfull circles, and are then separated from each other by corresponding thinner strips of flexible material 3, 3, 3 and are arranged in connection with top and bottom strips 5, 5 of the' conformation shown.

In constructing this tube after the perforations 4 have been made the strips 2 and 3 are all secured together in alternate relation by any well known method. of sealing', as by sel -sealing cement, and the'joints made absolutely air tight by any preferred method of hemnetical sealing. -This tube as thus composed has its ends joined together by sealing it in any preferred manner so as to make a complete circular tube haring hermetically sealed cells radially located in such manner as to give the best elasticity from. the material from which it is made, and also in such manne-r that the elastic effect of at niospheric air at normal'pressure is utilized, it being understood that my novel tube is distinctly a tube designed for use with the confined air in the cells at normal air pressure only.

I do not limit myself to the especial form of structure shown in the accompanying;

`drawings as the same may be departed from in many instances and still come within the terms of my claims hereinafter made, but

4I ldo lay special importance upon the construction of a tube in which a series of openings 4:, 4, t are employed with their diameters extendingin radial directions of ,the tube in contradistinctionto a tube in Y of the tube, and I lay claim to no such st|urture, my invention being directed to a cellular tire in which the. individual cells thoreof are radially located and 'rendered capable of utilizing the elasticity of the air and the material of which the tube is made in the best possible manner.

Having thus descriiied I ny invent-ion what I claim and desire/5o secure by Letteifs Patent of .the United States isl. A tire for Wheeled 'vehicles comprising superimposed concentric layers of soft 1Yub- "ber, the alternate layers of which are provided 'with radially' eX'tending perforations,

A:und the intermediate layers secured to the adjacent faces of the ,first-mentioned layersand adapted 1go seal the open ends of said perforations.

2. 'A tire for Wheeled vehicles comprising superimposed concentric 1a ers of soft rubbei", 'the alternaieiiiyers o which are provided with radially extending perforations; and the intermediate layers secured to the `adjacent faces' ofthe first-mentioned layers and adapted' to seal the open ends of said pefoi'ations; the perforations in the alternate layers being staggered with relation rto each other.' t f j 'In `iaes'timony whereof I have signed iny
